awk and Unary Operators in Bash

I am getting the following error

Code:
/home/hagbard/chaos/resip/ictja/siculet-0.0.0/amvib/tmspan.sh: line 135: BEGIN {printf "%.0f", int((tm-(thh*60.0*60.0))/60.0)}: No such file or directory
/home/hagbard/chaos/resip/ictja/siculet-0.0.0/amvib/tmspan.sh: line 138: [: -lt: unary operator expected

The code is this

Code:
  hh=`awk -v tm=$ftm  \
    'BEGIN {printf "%.0f", int(tm/(60.0*60.0))}'`
  mm=`awk -v tm=$ftm -v thh=$hh  \ 
    'BEGIN {printf "%.0f", int((tm-(thh*60.0*60.0))/60.0)}'`
  ss=`awk -v tm=$ftm -v thh=$hh -v tmm=$mm  \
    'BEGIN {printf "%.0f", int(tm-(thh*60.0*60.0)-(tmm*60.0))}'`
  [ $hh -lt 10 ] && hh="0${hh}"
  [ $mm -lt 10 ] && mm="0${mm}"
  [ $ss -lt 10 ] && ss="0${ss}"
  ftm="${hh}:${mm}:${ss}"

What a funny thing, it happens that an error occurs whenever there are spaces after the continuation backslashes \

Test::use::ok(3)					User Contributed Perl Documentation					  Test::use::ok(3)

NAME
Test::use::ok - Alternative to Test::More::use_ok SYNOPSIS
use ok 'Some::Module'; DESCRIPTION
According to the Test::More documentation, it is recommended to run "use_ok()" inside a "BEGIN" block, so functions are exported at compile-time and prototypes are properly honored. That is, instead of writing this: use_ok( 'Some::Module' ); use_ok( 'Other::Module' ); One should write this: BEGIN { use_ok( 'Some::Module' ); } BEGIN { use_ok( 'Other::Module' ); } However, people often either forget to add "BEGIN", or mistakenly group "use_ok" with other tests in a single "BEGIN" block, which can create subtle differences in execution order. With this module, simply change all "use_ok" in test scripts to "use ok", and they will be executed at "BEGIN" time. The explicit space after "use" makes it clear that this is a single compile-time action. SEE ALSO
